NNT (Nicotinamide Nucleotide Transhydrogenase): NNT is an enzyme located in the mitochondrial inner membrane, involved in the regeneration of NADPH from NADH. This process is crucial for maintaining the cellular redox state and protecting cells from oxidative stress. Deficiencies in NNT can lead to impaired mitochondrial function and increased susceptibility to oxidative damage, contributing to metabolic disorders and chronic diseases....
